LT-1 Maf and Translator

[gusszgs]

Hey guys, I just upgraded to a new Translator and LT-1 maf (always seems like I'm 20 yrs behind)
I'm running petty much stock with some nice bolt on's ...........TE-60, Fairpark SLIC, RJC DP, with Razor's alky and TT chip.
My question is, would it be best to leave the translator box alone and make any parameter adjustments through the chip? Seems kinda rich at idle and somewhat slow to spool up in 1st gear. Which I expect as I'm running the stock D5 right now. Just wondering if I can make an adjustment in the box to help with the 1st gear spooling.

It only takes a second to turn the knob and see.

I think you're better off letting the TT chip do it's thing and adjust through the chip. If you had an Extender chip you could utilize the Translators features more, but I think the TT pretty much over rides the Translator. At least that's the way I understood it.

Pretty much what he said but the WOT setting will make the fuel ramp in quicker but the WOT fuel is static through the chip. What are your BLs at idle that makes you think it's rich? If it truly is rich, that can be adjusted by the BASE setting in the translator. Let's hear what the BLs are first though before you go changing anything.

Had the car out tonight and the BL's are 130-132. What makes me think it's rich is my nose and my clothes reek of fuel after a drive. I understand the BL's look pretty good. No cat, so is this just the nature of the beast?

With those numbers, it's adding fuel for a lean condition. Possible vacuum leak?? What is your base fuel pressure at? Should be 43 psi vacuum line off the regulator.

Also... to your original question... you wanna help spool in low gear... take out 15% fuel in 1st gear and add 2-3* of timing for 1-2 gear. But get your slightly lean condition figured out first.

The FP is bang on 43psi. The BL'S are 130 most of the time but did see it at 132 once

With BLM numbers that good, I wouldn't touch a thing. Most of what you smell as richness is likely due to the open loop idle feature in your chip. With open loop idle the car is running rich, most open loop idle Air Fuel ratios are in the low 13:1 range, and I've seen some in the 12:1 ranges.

Yep. Probably nothing wrong.

Ok thanks to all for the responses. The car runs fantastic, seems even stronger now with the trans and lt1 maf.

 

[earlbrown]

It probably is. Just because a car ran 'well' with an original MAF doesn't mean it was running 'right'.

 

[gusszgs]

Actually I did have a remand maf on there before I did the switch. Car ran ok with it but I'd never see 255 AF numbers at wot. 238 is what I recall max.

Sounds like you had one of the 95% of remans that don't read right.
